Taking a supplement of vitamin D in combination with your prescription asthma medicine may halve your risk of an asthma attack that would require hospitalization, according to a new meta-analysis from Queen Mary University in London (QMUL). A vitamin D deficiency alone, which is rather common at northern latitudes, can increase the risk of asthma. Therefore, it is vital to make sure to have sufficiently high levels of this nutrient all year round to protect your respiratory tract.

Decades of intensive farming have depleted the soil. As a result, crops lack up to 40% of their essential nutrients, according to a previously published study from University of Texas and a more recent one from Switzerland. Even if you stick to the official dietary guidelines, you may have difficulty with getting enough calcium, selenium, zinc, iron, vitamin B2, vitamin C, and other essential micronutrients that are required for good health.

- and help prevent dementia, depression, and impairment of your cognitive skills

People with elevated levels of omega-3 fatty acids in their blood have better circulation in those parts of the brain that handle learning, language, memory, and other cognitive functions, according to a recent report that is published in the Journal of Alzheimer’s Disease. The scientists also observed a link between blood levels of omega-3 and the rate of dementia and depression. They call their study an important discovery that supports earlier studies, which have shown how simple dietary adjustments such as increasing your intake of oily fish or fish oil supplements help preserve mental skills and a healthy mind.

British scientists have tested whether omega-3 fatty acids from fish oil supplements have a pain-relieving effect on patients with rheumatoid arthritis. As it turns out, consuming fish oils with large quantities of EPA and DHA has the best effect, so make sure to read the label to see how much of the two omega-3 fatty acids your supplement contains. Rheumatoid arthritis and other rheumatic diseases are a result of joint inflammation, so it may also pay off to look into the benefits of an anti-inflammatory diet.

Three recent studies show that vitamin C may enable genes to kill uncontrolled stem cells that cause leukemia, thereby giving the nutrient a role in cancer prevention. However, it takes more than a few oranges or vitamin C in tablet form to obtain this therapeutic effect. It requires intravenously administered vitamin C in large quantities. These doses have been used for decades and are known as redox therapy. Here, vitamin C works by entirely different mechanisms and effectively kill off cancer cells.

Three American researchers were awarded the Nobel Prize in Physiology for their discovery of the molecular mechanisms that control our 24-hour rhythm and the ticking of the cellular clocks. Lack of sleep can lead to overweight, type 2 diabetes, cardiovascular disease, Alzheimer’s disease, and cancer, which is why it is vital to get to bed at a proper time. If you have difficulty with falling asleep or cannot sleep through the night, supplements of melatonin serves as a natural sleeping pill that comes in handy.

There is absolutely no reason not to consume eggs, meat, butter and other cholesterol-filled foods with a good conscience. American dietary guidelines have finally exonerated cholesterol, which happens to be an essential compound. Many scientists actually claim that atherosclerosis and cardiovascular disease are both a result of inflammation and lack of specific micronutrients. It is important to pay attention to factors that are known to promote inflammation in the body and take the necessary steps by looking after your circulatory system, making healthy lifestyle choices, and possibly even using supplements.

It is essential that your heart is able to pump optimally throughout life. A study from Medical College of Georgia, Augusta University, the United States, has just shown that a diet with low levels of vitamin K1 from dark, leafy greens increases your risk of an unhealthy enlargement of the heart’s left ventricle that pumps the oxygenated blood to the aorta (the body’s largest artery). The scientists even observed this enlargement in teenagers. Vitamin K1 is primarily known for its role in the blood coagulation process, but it is also converted to vitamin K2 in our gut flora. In fact, it is vitamin K2 that is important for the heart and cardiovascular system.

More and more studies show how important our digestion and gut flora are for our health and mood. A new study published in Scientific Reports reveals that omega-3 fatty acids are able to influence positively the diversity of our gut flora.

There is a link between low blood levels of trace elements like zinc and early stages of diabetes, according to Russian research published in Journal of Trace Elements in Medicine and Biology. A large number of people are believed to have diabetes without knowing it. One of these early stages of diabetes is insulin resistance, a condition where the cellular uptake of sugar is impaired. Another is metabolic syndrome that includes hypertension, elevated cholesterol levels, and a characteristic apple-shaped figure with too much abdominal fat. The question is, how do we get enough zinc, and why do so many people appear to be deficient in this essential trace element?

If you consume too much red meat it may increase your risk of colon cancer, but is there meat with the opposite effect? According to a new and groundbreaking study, eating salmon or other good sources of omega-3 fatty acids appears to help prevent this rather common cancer form and possibly even other cancers, as well. Just make sure not to get too much omega-6, especially from margarine and other plant oils, as it is vital to have the correct balance between the two types of fatty acids.

The number of children diagnosed with autism has increased steadily over the past decades, and a number of factors can cause the disease. Now, scientists from the University of California and other institutions in the United States have discovered that pregnant women who get the recommended amount of folic acid or increase their intake right around the time of conception have a lower risk of giving birth to a child that develops autism caused by pesticide exposure.
